FOLDING BOX.

SPEIFICATIOT forming part of Letters Patent No. 317,795, dated May 12, 1885.

Application filed January :22, 1885. (No model.)

To all whom it may concern:

Be it known that I, GUSTAV L. JAEGER, a citizen of the United States, residing at New York, in the county and State of New York, have invented new and useful Improvements in Folding Boxes, of which the followingisa specification.

In the manufacture of collapsible boxes, wherein diagonal creases are used to afford the capability of collapsement, it has been customary to form such creases directly inthe body of the sides or ends. In such construction the creases are always visible, detracting from the appearance of the box; they also weaken the sides or ends in which they are formed, necessitating the use of stiffeningflaps, it it be desired to securely hold the expanded box in shape. In this invention such folding creases are formed in the pasting flaps, a diagonal crease being formed in each such flap, one-half thereof being then pasted to the proper ends or sides which cover and protect such creases when the box is expanded, and act also as stiffeners to aid in maintaining the expanded box in shape. This and the other features of the invention are more fullyhereinafterdescribed and claimed, reference being had to the drawings, in which- Figure 1 represents a blank from which I make my folding box. Figs. 2,3,and i show the diiiferentstagesthroughwhichtheblankpasses. Fig. 5is a transverse section of the box when partly unfolded, the plane of section being indicated by the line 00 m, Fig. 6. Fig. 6 is a plan or top view of the same. Fig. 7 is a perspective view of the box when completed. Fig. 8 is a plan or top view of the same. Fig. 9 is is a plan of the partition when folded. Fig. 10 is a transverse section of the box without the multiple partition, the plane of section being indicated by the line 3 y, Fig. 8.

Similar letters indicate corresponding parts.

In the drawings, the letterA designates the bottom, B B are the the ends, and D D are the sides, of the blank, which is cut out of pasteboard or other equivalent material in the form shown in Fig. 1, and which is creased in the lines a I) c d e. The sides D D are provided with extensions E E E E, which are creased in the diagonal lines fff f, so that the outer sections, 9 g g g, of said extensions can be folded in, as shown in Fig. 2. These outer sections form the pasting-flaps,andafter paste has been applied to them the sides D D are folded in (see Fig. 3) and pressed down, so that the pastingflaps g 5 g g adhere to the ends B B. After .the paste has set the box is ready for use. since by lifting the sides D D up to a vertical position (see Figs. 5 and 6) the ends B B are gradually raised to a vertical position, and they are retained in this position by the contents of the box; but in order to retain them in position before the box is filled I- can apply stiffening-flaps S to the ends, of-t-he box, one such flap being shown as applied to the end B. By folding this flap in, as shown in Fig. 14, the box is retained in its expanded position. A similar stiffening-flap may be applied to the end B of the box. The stiffening-flaps S are provided with side extensions, 8 s, which,-when the flap is folded in, engage with slots 8 s in the sides of the box, so as to lock the stiffening-flap.

In the example shown in the drawings a folding top, 0, is applied to the end B, and when this top is folded down, Fig. 8, the box is closed. On the outer end of the top 0 is formed the locking-flap F, which is provided with a tongue, h, and if this tongue is passed into an opening, '11, in the end B the topis locked. For transportation the box is folded up, as shown in Fig. 4.

The great advantage of 'my box is due to the great economy of its manufacture and the ease with which it can be folded and unfolded, and these qualities are chiefly due to the diagonal creasesffff. By means of these diagonal creases the pasting-flaps g g g y can be readily brought in position to receive paste, and by providing a proper tool the paste can be applied to all the pasting-flaps simultaneously, and after the paste has been applied the sides D D are folded in and then the top 0 is broughtto the position shown in Fig. 4, and by exposing the whole to pressure the pasting-flaps adhere to the ends B B and the box is ready for transportation, and when it arrives at its place of destination it can be unfolded for use almost instantaneously.

With my folding box is combined a multiple partition, G, which is capable of being folded up, as shown in Fig. 9, or to be expanded, as shown in Fig. 7, and which, when expanded, fits the interior of the box and forms a brace whereby the box is prevented from collapsing. The construction of the multiple partition is well known, and requires no further description. \Vhen this partition is placed into the box, it forms a series of cells for the reception of eggs or other articles. In the top Gis afinger-hole, j, and when the top is closed down and locked the finger-hole comes directly over one of the transverse strips of the multiple partition G, so that said strip can be grasped and the box,together with its contents, can be lifted out of the packing-case and carried from one place to another. In order to render this operation feasible, it is necessary that the top shall be securely locked in its closing position, otherwise if the box is lifted up, as shown and described, the weight of the contents of the box would be liable to force the top open and the contents would become injured.

That I claim as new, and desire to secure by Letters Patent, is

1. A collapsible box having diagonal folding creases in its pasting-flaps, substantially as described.

2. A collapsible box having diagonal folding creases in its pasting-flaps, and having stiffening-flaps formed as extensions of its ends and adapted to be folded in for holding the expanded box in shape, substantially as described.

3. A collapsible box composed of a bottom and a top, folding sides, and pasting-flaps 5 formed as extensions of two of the sides, and having diagonal folding creases formed therein, substantially as described.

at. A collapsible box composed of a bottom and a top, folding sides, pasting-flaps formed as extensions of two of the sides and having diagonal folding creases formed therein, and stiffening-flaps adapted to be folded into the box and maintain it in position when expanded, substantially as described.

5. In a collapsible box, the combination of a top and bottom, A 0, sides 13 B D D, and pasting-flaps E, the latter having diagonal folding creases f, substantially as described.

6. In a collapsible box, the combination of a top and bottom, A 0, sides B B DD, pasting-fiaps E, having diagonal folding creases, f, and stiffening-flaps S F, substantially as described.

7. The combination of a collapsible box 5 having diagonal folding creases in its pastingflaps, and a collapsible partition adapted to be placed therein, dividing it into compartments and maintaining itin expanded shape, substantially as described.

In testimony whereof I have hereunto set my hand and seal in the presence of two subscribing witnesses.
